Roger Waters/David Gilmour

It's a testament to the songwriting partnership behind Pink Floyd's greatest successes that Roger Waters and David Gilmour managed to yield everything from stadium-rattling prog masterpieces like The Great Gig In The Sky and Shine On You Crazy Diamond to bonafide, chart-dominating hits like Another Brick In The Wall (Part 2).

From ethereal to anthemic, heavy to soft, they are masters of dynamics - and brave with it, too.
